Pro of doing the PCV reroute or delete on a 2015 duramax, I'm guessing the PCV delete means it gets vented to atmosphere?

Delete, would be sealing it off.
Not good.

Re route takes the gasses out of the intake flow.
Where it's not really a problem, IMO.

It's when the oil vapor residue mixes with the EGR, creating an asphalt-like coating.
Remove the exhaust gas component, no goo created with any oil present.

So the reroute essential turns it into a breather and vents it to atmosphere?
yes, the PCV from the factory runs into the intake and gets reburned, the reroute takes the PCV to the atmosphere.

There are some that reroute thru a catch can (oil trap), then back to the intake, turbo sucking it in and thru.
Others, vent to atmosphere.
